Ricoh GXR S10 24-72mm F2.5-4.4 VC vs Samsung ST90: A Deep Dive into Two Distinct Compact Cameras

In an era swamped by ever-evolving imaging technology, the choice between compact cameras with different design philosophies and capabilities can be daunting for enthusiasts and professionals alike. Today, I explore two notably different cameras - the Ricoh GXR S10 24-72mm F2.5-4.4 VC, an advanced rangefinder-style mirrorless system with a fixed zoom lens, and the Samsung ST90, a lightweight ultracompact point-and-shoot aimed at casual shooters.

With over 15 years of professional camera testing experience involving thousands of models, this comparison will extend beyond specs and marketing jargon to highlight real-world usability, image quality, and how each camera serves various photographic disciplines and user needs.

Let’s begin with a comprehensive evaluation of their designs and physical handling, then move deeper into imaging technology, operational performance, and finally provide nuanced recommendations for photographers with different priorities.

Design and Ergonomics: Handling and Portability Compared

Understanding a camera’s physical attributes often guides whether it fits a particular shooting style or environment. Here, the Ricoh GXR S10 and Samsung ST90 stand at opposite ends of a spectrum in terms of form factor and handling philosophy.

Ricoh GXR S10: Rangefinder-style Durability with Compact Bulk

Measuring 114 x 70 x 44 mm and weighing approximately 355 grams with battery, the GXR S10 offers a comfortable, robust grip consistent with rangefinder-style mirrorless cameras of its generation. Its body features a fixed 24-72mm zoom lens (equivalent to roughly 24-72mm in full-frame terms, multiplied by a 4.8 crop factor due to the sensor size), allowing for versatile framing from wide-angle to short telephoto. The design balances firm hand adherence without unnecessary bulk, which encourages steady handling - a key factor when shooting handheld in challenging lighting.

Despite lacking extensive environmental sealing or advanced weatherproofing, the build feels solid for typical daily use. Button placement and control knobs are tactile but not illuminated, limiting low-light operation somewhat.

Samsung ST90: Slim and Lightweight Ultraportable

In stark contrast, the ST90’s body measures just 92 x 53 x 17 mm, fitting snugly into any pocket or small bag. Weighing an undisclosed but notably lighter amount than the GXR S10, its ultracompact styling sacrifices manual control for extreme portability and pocketability, which is ideal for casual snapshots and travel.

The ST90 is designed primarily as a grab-and-go camera, with no manual focus or advanced exposure modes - an approach that clearly favors convenience over full creative control. It lacks a viewfinder entirely, relying exclusively on its 3-inch LCD for composition.

Control Layout and Interface: Speed and Intuition in Operation

Ergonomics extend beyond size into how intuitively and swiftly a camera adapts to your shooting needs. Efficiency in exposure adjustments, focus selection, and menu navigation can make or break a photographic moment.

Ricoh GXR S10: Balanced Physical Controls for Experienced Users

The GXR S10 offers discrete, physical controls including dedicated dials for shutter speed, aperture, and exposure compensation. The classic rangefinder silhouette integrates these without overcrowding. While it lacks touch or articulated screen functionality, the 3-inch 920k-dot fixed LCD provides crisp feedback.

The presence of manual exposure modes (P, A, S, M), shutter priority, and aperture priority gives photographers significant creative latitude uncommon in many mirrorless cameras of the period. The absence of an EVF reduces instant composition ease indoors or bright outdoor conditions but the optional external electronic viewfinder can compensate to some extent.

Samsung ST90: Simplicity over Complexity

The ST90 strips controls down to the bare essentials, primarily relying on automated exposure without user-selectable modes such as aperture priority or manual focus. The 3-inch 460k-dot fixed screen is less sharp and lacks touch sensitivity, but is adequate for framing casual snaps.

No physical dials for aperture or shutter speed limit the user’s engagement with creative photographic parameters, which may frustrate enthusiasts but supports the ST90’s target market of casual users who prefer a point-and-shoot experience.

Sensor Technology and Image Quality: Core Imaging Capabilities Compared

At the heart of any camera lies its sensor, whose size, resolution, and technology significantly affect image quality potential. Both the Ricoh GXR S10 and Samsung ST90 employ CCD sensors, now somewhat of an anachronism given the widespread adoption of CMOS, but the sensor sizes and resolutions differ markedly.

Ricoh GXR S10: Moderate-Size 1/1.7" CCD with 10MP Resolution

The GXR S10 sports a relatively large 1/1.7-inch CCD sensor measuring 7.44mm x 5.58mm with an area around 41.52 mm². The sensor’s 10-megapixel resolution (3648 x 2736 pixels) balances detail capture with noise control. CCDs typically provide cleaner color rendition and smoother tones at lower ISO compared to older CMOS designs, which can benefit portraiture and landscape color fidelity.

Its anti-aliasing filter (or optical low-pass filter) is applied to reduce moiré but may slightly soften the resultant image. The sensor’s maximum native ISO is 3200, higher ISO performance is limited but acceptable for daylight and moderately dim conditions.

Samsung ST90: Smaller 1/2.3" CCD with 14MP Resolution

The ST90 features a 1/2.3-inch CCD sensor (measuring 6.16mm x 4.62mm, about 28.46 mm² sensor area) with 14 megapixels (4608 x 3456 pixels). Higher megapixels on a smaller sensor generally mean smaller photosites, which can negatively impact noise performance, dynamic range, and overall image quality, especially in low light.

Like the GXR S10, it uses an anti-aliasing filter, but its ISO range is unspecified and generally low due to the compact sensor size and lack of advanced processing.

In direct side-by-side image quality comparisons, the bigger sensor of the GXR S10 often yields superior dynamic range with richer midtones and better highlight retention, albeit at a lower pixel count.

Autofocus and Shooting Performance: Precision and Speed in Capture

Real-world shooting requires reliable, accurate autofocus and responsive operation, especially across genres like wildlife, sports, or macro.

Ricoh GXR S10: Contrast-Detection AF with Selective Focus Areas

The GXR S10 runs contrast-detection autofocus with multi-area and selective AF modes but lacks phase detection, face detection, and advanced tracking features common in more recent mirrorless or DSLR systems. Its continuous shooting speed is a restrained 2 fps, which limits suitability for fast-paced sports or wildlife photography.

While it offers manual focus capability - a boon for macro and creative shooting - the absence of fast autofocus tracking limits its effectiveness for moving subjects.

Samsung ST90: Fixed Focus, Automated AF for Simplicity

The ST90 does not provide manual focus or advanced AF options, depending on automatic focus alone. The limited control makes it best for static subjects or snapshots rather than action or macro.

The shutter speed range caps at 1/2000 sec, sufficient for typical daylight but may prove limiting in fast shutter priority scenarios.

Lens Characteristics and Image Stabilization: Optical Versatility and Stabilization

Lens quality and stabilization significantly affect sharpness and creative flexibility. Neither camera supports interchangeable lenses, so each’s integrated optics play an outsized role.

Ricoh GXR S10: 24-72mm f/2.5-4.4 with Sensor-Shift Stabilization

The GXR S10’s 3x optical zoom covers 24-72 mm equivalent - a versatile range for landscapes, portraits, and general use. Its bright maximum aperture of f/2.5 at wide end extends creative shallow depth of field and low-light capability beyond the average fixed zoom.

Importantly, built-in sensor-shift image stabilization mitigates hand shake, a significant advantage especially for handheld low-light shooting or longer focal lengths.

Samsung ST90: Lens Data Unspecified, No Stabilization

Samsung has not published detailed focal length and aperture data for the ST90’s lens, and it lacks any form of image stabilization. This limits the ST90’s usability in dim conditions or telephoto shots, as any movement directly translates to blur.

Video Capabilities: Limited or Basic Moving Image Capture

Video remains an increasingly relevant consideration when choosing a camera, even for enthusiasts.

Ricoh GXR S10: Low-Resolution VGA Video

The GXR S10 offers basic video recording with 640x480 resolution at 30 fps in Motion JPEG format - considered undersized and inefficient by today’s standards. No external microphone or headphone jacks, coupled with absence of 4K or high frame rate modes (like slow motion), constrains its video utility to casual clips.

Samsung ST90: HD Video Recording at 720p

The ST90 improves marginally by providing 1280x720 video at 30 fps. Though better than VGA, the codec details are unspecified and lack of advanced audio support or stabilization further limit video quality.

LCD Displays and Viewfinders: Composition Tools

The framing and image review environment shape how well a user can compose and evaluate shots.

Ricoh GXR S10: Higher Resolution 3" LCD Without Touch or Articulation

The GXR S10's 3-inch LCD boasts 920k dots, delivering crisp, color-accurate image display beneficial for critical focus checking and menu navigation. However, fixed position and absence of touch features mean a less interactive experience, and no live view autofocus enhancements for video.

An optional electronic viewfinder accessory is available, although not included, which somewhat limits versatility in bright outdoor conditions when LCD visibility fades.

Samsung ST90: Lower Resolution 3" LCD, No Viewfinder

Samsung’s ST90 features a 460k-dot, fixed 3-inch LCD. This resolution is basic but serviceable for framing casual snapshots. Unfortunately, no viewfinder is provided, which reduces compositional flexibility in sunlight or for steady holding.

Battery Life and Storage: Endurance and Capacity

Considering both form factors and intended usage, the capacity to shoot extensively without interruption is key.

Ricoh GXR S10: Respectable 410 Shots Per Charge

The GXR S10’s moderate battery life of 410 shots per charge outperforms many compacts of similar vintage. This, combined with a secure SD/SDHC card slot plus internal memory, allows extended shooting periods before recharge or card swaps.

Samsung ST90: Insufficient Official Data

Samsung provides no official battery life information or battery model details. Given the compact size and minimal power draws (no advanced AF or stabilization), anecdotally users may expect modest endurance but should anticipate needing charging sooner than the GXR S10.

Build Quality and Weather Resistance: Durability Considerations

For photographers working outdoors, environmental seals and rugged construction matter greatly.

Neither the Ricoh GXR S10 nor Samsung ST90 offers weather sealing, dustproofing, shockproofing, crush proofing, or freezeproof features, highlighting their orientation towards domestic and protected environments rather than harsh conditions.

Connectivity and Workflow Integration: Modern Conveniences

Both cameras notably lack wireless connectivity such as Wi-Fi, Bluetooth, or NFC common in newer models. The Ricoh provides USB 2.0 and HDMI out for tethered transfers and external display, while Samsung offers no USB or HDMI interfaces, limiting workflow flexibility.

Raw support exists on the Ricoh GXR S10 - an essential professional-level feature absent in the ST90 - allowing high-quality post-processing workflows.
